With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings:

Figure 1 is a plan view illustrating a panel reflector constructed in accordance with the invention.

Fig. 2 is a rear elevational view thereof.

Fig. 3 is a front elevational view of the reflector as supported on andirons.

Fig. 4 is an enlarged plan view of one end of the device.

Fig. 5 is a perspective view of the friction collar and ratchet wheel connected with the lower edge thereof.

Referring to the drawing in detail, the device comprises a body portion including a central section 5 and end sections 6 and 7. The central section embodies a pair of plates 8 and 9, the rear plate 8 being provided with upper and lower elongated openings 10 through which bolts 11 extend, the bolts also passing through openings in the plate 9. These plates 8 and 9 are arranged in overlapped relation with respect to each other so that they may be adjusted longitudinally for positioning on andirons or fire grates of various sizes, the bolts providing means for securing the plates 8 and 9 in their positions of adjustment.

The end section 6 also embodies overlapped plates 12 and 13, the plate 12 having elongated openings 14 in which the adjusting bolts 15, which also pass through openings of the plate 13, are positioned, the bolts holding the plates 12 and 13 in their adjusted positions.

The reference character 16 indicates hinges that conmeet the plate 8 of the central section 5 and the plate 12 of the end section 6, so that the end section '6 may pivot with respect to the central sectionS.

Arms17 are arranged at the upper and lower edges of the plate -13 and extend laterally from oneend'thereof,

the arms -17-providing a support for the winding roll 18 which is provided with a crank handle 19'for effecting rotation of said winding roll 18, for purposes to be.hereinafter more fully described. Ratchet teeth 20 are formed -on one end of the winding roll'18 and cooperate with the ,pawl' 2l carried by the upper arms 17, in preventing reverse. movement of said winding-roll, to'the endthat the foil stretched over the device may be maintained taut.

A coiled spring 22 is disposed between the lower arm 17 and one end of'the winding roll '18, the spring'normally-biasingthe winding roll upwardly so' that'the ratchet teeth 'aretnormallylheld'in engagemenrwith the pawl 21. The end section '7 also embodies overlapped plates 23 and "24, 'the plates"23 having elongated openings26 in which the bolts 27 are disposed, the bolts 27 jpassing through openings in theplate'24'so that when the .nuts 28 which "are threade'd-on the ends of the bolts 'aretightened, the .plates will 'be securely held together in adjusted positions.

.Arnis29 are secured to the free end .o'f fth'e,plate24 adjacent to the upper and lower edges thereof, the arms '29 providing asuppott'for the-roll 30 on whichtherloll of foil is wound in the original package.

A ratchet wheel '31 is secured'to one end of'the roll 30, to which the. split collar 20' is secured, the collar-'20 Fbeingsecured around shaft'21 onw'hich the .roll 30 is mounted. The split collar is secured :to shaft 21 by means of bolt 25' so that-friction is set up between roll 30 and its shaft'21' to prevent rotation of the roll 30 under hormal conditions, butallow slippage ofithe roll under iexcessive winding strain directed to roll 30, durin g'unwinding of the foil strip from said roll- 30.

, .Each of the a'rmsf17 and '29ispro'vided with a .cutbutportion in whicha pivoted ,plate 33 is mounted, each plate33 "being formed with abearing3'4 that cooperates with the bearing 35 formed in its supporting arm, to the end that these pivot plates may be swung outwardly providing clearances so that the shafts on which the winding roll 18 and roller 30 may be readily and easily removed or positioned. Latches 35 are provided for holding the pivoted plates 33 in position for supporting said roll.

Rollers 36 are supported in openings formed in the hinges 16 and 37 which connect the end sections of the body or frame to the central section 5.

Extending forwardly from the ends of the end sections 6 and 7, are guide bars 38, while extending forwardly from the central section 5, adjacent to the ends thereof are guide bars 39, the guide bars having outer rounded surfaces over which the foil strip which in the present showing is indicated by the reference character A, moves. Adjustably secured to the rear surfaces of the sections 6 and 7, are brackets 40, adapted to be secured to the andiron bars or fireplace coal grate arms for supporting the device in its proper position Within the fireplace.

Arms 41 are adjustably secured to the brackets 40 and have adjustable connection with the end sections 6 and 7 through the medium of elongated openings 42 and bolts 43 which extend through the end sections and elongated openings where they are supplied with securing nuts 44.

When threading the foil sheet through the body or frame, the foil is passed over the guide bars 38 of the end section 7 and then passed between the hinges 16 and over the roller 36, connecting the section 6 with the central section 5. The strip is now passed forwardly and moved across the central section 5 over the guide bars 39, from where the strip passes between the hinges 37 and over the roller 36 adjacent to the section 6 from where the foil strip is moved over the bars 38 and wound on the winding roll 18.

From the foregoing it will be seen that due to the construction shown and described, I have provided a heat and light reflecting panel which may be readily and easily mounted on andirons or fireplace coal grates so that a heat and light reflecting panel is provided at the rear of such andirons or coal grate, to reflect light and heat waves forwardly, thereby to obtain the maximum heat from a given quantity of fuel.

It will also be seen that when the reflecting surface becomes damaged or otherwise rendered defective, the foil may be Wound onto the winding roll 18 until a new length of foil is stretched across the body or frame.
